Mobile Telehealth Systems: Accessibility and Security Challenges

The rapid expansion of mobile telehealth systems during the COVID-19 pandemic enabled continuity of care but exposed significant challenges in accessibility and security. Accelerated deployment timelines often prioritized functionality and scale over critical non-functional requirements, leading to reduced accessibility for users relying on assistive technologies and increased exposure to security and privacy risks. This paper examines how deployment speed influences accessibility compliance and system security in mobile telehealth environments. We introduce a quantitative model, the Deployment-Accessibility Debt Index (DADI), to capture the tradeoff between rapid deployment and accessibility degradation. Using an empirical analysis of 36 emergency telehealth systems, we observe a substantial decline in accessibility compliance and assistive technology compatibility during peak deployment periods. In parallel, we highlight key security concerns, including data protection gaps, authentication weaknesses, and risks associated with rapid cloud-based integrations. To address these challenges, we propose the Rapid Accessibility Compliance Protocol (RACP), a structured framework that defines a minimum accessibility baseline, phased remediation strategy, and post-deployment consolidation. We further discuss how integrating secure design principles with accessibility governance can improve resilience and inclusivity in mobile telehealth systems. The findings emphasize that accessibility and security must be treated as foundational requirements rather than optional enhancements, even under emergency deployment conditions.
